Since May 13th, with the temperature rising and the weather getting warmer, the eastern part of Inner Mongolia has entered the peak period of agricultural irrigation. The State Grid Inner Mongolia Eastern Power Co., Ltd. carried out the big data analysis and comprehensive operation and maintenance of the 2018 agricultural irrigation peak distribution network. In detail, we will grasp the recent and historical operation characteristics of the power supply equipment and facilities of the well, carry out the prediction of the well load, and do the operation and maintenance of the relevant equipment to ensure the reliable power supply of the agricultural irrigation peak.
It is understood that the seasonal characteristics of the distribution network load of Mengdong Power Grid are obvious, and the peak load of agricultural irrigation has certain influence on the safe and stable operation of distribution network facilities. According to statistics, in the past five years, the abnormal operation problems such as the low voltage, heavy overload and unbalanced three-phase load of the public network of Mengdong Power over 80% occurred in the peak period of agricultural irrigation load from May to August. With the launch of the “Two Years of Attacking the Wells and Powering Projects with the Agricultural Network Projectâ€, the company took this opportunity to continuously improve the coordinates of the newly commissioned agricultural distribution network equipment information system, the entry of the graphical system of the account, the establishment of the model, etc. Informatization work, and integrate PMS production management system, electricity collection system, dispatch power quality system and other platform information, combined with the construction of power supply service command platform, carry out normalized distribution network operation big data monitoring and analysis, fully exploit the value of big data, Timely effective maintenance and repair of hidden dangers, defects and abnormal operation of the distribution network facilities.
Through analysis, the company discovered the potential risks of agricultural irrigation power facilities in a timely manner and completed targeted governance. From April 1st to May 9th, a total of 9747 safety hazards such as low-voltage reactive power compensation device failure, low-voltage outlet aging, and tree barrier were eliminated, and AVC parameter adjustment, distribution gear position adjustment, and variable platform low-voltage load adjustment were completed. The station has adjusted and solved 11 overloaded 10 kV distribution lines and 636 distribution transformers, which provides a reliable guarantee for the agricultural irrigation peak.
In the next step, State Grid Mengdong Power will carry out special operation and maintenance and analysis for the peak irrigation period, further strengthen the inspection and maintenance work of equipment infrared temperature monitoring, reactive equipment monitoring, etc., and carry out statistical analysis of fault repair of machine power supply facilities on a monthly basis, and at any time. Adjust the distribution network operation plan. In addition, the 9 county companies affiliated to the company set up a leading group for agricultural irrigation and power conservation, and each power supply station set up a farm irrigation and power conservation service team. The employees of the power supply company went deep into the field and combined with the safety inspection and inspection activities. Electric poles, drain lines and other equipment for comprehensive special inspection and overhaul, find problems in a timely manner, and make every effort to ensure stable equipment and safe use of electricity during the irrigation period.
